Salivary gland tumors in children

Fewer than 5% of all primary salivary gland neoplasms occur in children, but if benign supporting tissue tumors are excluded, a higher proportion than in adults are malignant. The first decade of life, and particularly the first 2 years of life, has a preponderance of benign neoplasms. Commencing with the second decade, carcinomas rise in incidence and are most often mucoepidermoid and acinic cell carcinomas. The pleomorphic adenoma is the most common epithelial salivary tumor throughout childhood. The embryoma may be a uniquely childhood epithelial salivary gland tumor.
